Match Column-$I$ and Column-$II$ with the correct relation:

Column-$I$	Column-$II$
$(i)$ Substitution reaction	$(p)$ $CH_2=CH_2 + Br_2 \to CH_2Br-CH_2Br$
$(ii)$ Addition reaction	$(q)$ $C_6H_6 + NO_2^+ \to C_6H_5NO_2 + H^+$
$(iii)$ Electrophilic addition reaction	$(r)$ $CH_3Cl + NaOH \to CH_3OH + NaCl$
$(iv)$ Electrophilic substitution reaction	$(s)$ $CH_3CH_2OH \xrightarrow[\Delta]{Al_2O_3} CH_2=CH_2$
$(v)$ Elimination reaction

(A) The correct matches are as follows:
$(i)$ Substitution reaction: $CH_3Cl + NaOH \to CH_3OH + NaCl$ (nucleophilic substitution) $\to r$.
$(ii)$ Addition reaction: $CH_2=CH_2 + Br_2 \to CH_2Br-CH_2Br$ $\to p$.
$(iii)$ Electrophilic addition reaction: $CH_2=CH_2 + Br_2 \to CH_2Br-CH_2Br$ $\to p$.
$(iv)$ Electrophilic substitution reaction: $C_6H_6 + NO_2^+ \to C_6H_5NO_2 + H^+$ $\to q$.
$(v)$ Elimination reaction: $CH_3CH_2OH \xrightarrow[\Delta]{Al_2O_3} CH_2=CH_2$ $\to s$.
Thus,the correct sequence is: $(i-r, ii-p, iii-p, iv-q, v-s)$.
